Disengaging ACC To disengage ACC, apply the brake pedal or move the ACC switch to off. ACC information on the HUD will not display when ACC is not engaged. Cleaning the System The radar can become blocked by snow, ice or dirt. If so, you may need to turn off the engine and clean the lens. Remember, don't use ACC in icy conditions, or when visibility is low, such as in fog, rain or snow. The lens is located on the driver's side of the front fascia. After cleaning the fascia lens, try to engage the ACC. If this does not fix the problem, you may have to remove the fascia lens and clean the inside of the fascia lens and radar lens. To clean the inside of the fascia lens and radar lens, insert a screwdriver or similar object into one of the small slots on the inboard side of the lens and pop the lens out. After cleaning the lens, set the lens back in place and press until it snaps in. Erasing Set Speed Memory When you turn the ACC switch or the ignition off, your ACC set speed memory is erased. Other Messages There are three messages that may appear in the Driver Information Center (DIC). They are SERVICE RADAR CRUISE, CRUISE NOT READY and CLEAN RADAR CRUISE. These messages will only appear to indicate a problem if ACC is active. See DIC Warnings and Messages on page 3-59 for more information. You may also see CRUISE SPEED LIMITED displayed in the HUD. See Head-Up Display (HUD) on page 3-29 for more information. 3-23
